I built a real-time electricity price API for Germany. It scrapes current tariff data and makes it available as JSON.
API endpoint: strom.nevik.de/api/
The API returns current electricity prices for any German postal code. No authentication, no rate limit (be reasonable), no tracking.
Example response for PLZ 10115 (Berlin):
Average price per kWh: ~35 cents
Cheapest tariff: ~28 cents
Grundversorger (default): ~42 cents
The difference is massive. A household using 3,500 kWh/year pays:
- Grundversorger: ~1,470 euros/year
- Cheapest tariff: ~980 euros/year
- Savings: 490 euros/year
The tool itself is at strom.nevik.de — you enter your PLZ and it shows live tariffs. The API powers it.
I'm sharing this because I think price transparency matters. Energy companies profit from customer inertia. The longer you stay without checking, the more you overpay.
If you want to use the API for your own project, it's free. If you want to build a similar tool, I'm in the Check24 affiliate program so I can share the integration approach.
The comparison tool: strom.nevik.de
The API: strom.nevik.de/api/
